A glass bubble carb cap for quartz bangers. The round dome sits on the mouth of the banger and makes the airflow circulate in the chamber, so the concentrate vaporizes evenly and does not stay burning on the edges.

The clear glass lets you see what is happening in the chamber, and the narrow neck gives a good grip even when hot.

Material: glass
Model: bubble carb cap
Suitable for: quartz bangers and oil bowls
